MIKI HOUSE Short-sleeved undershirt & Combination undershirt set Used during the newborn period. The size is 50cm, but I think it can be used up to about 60cm without any problems. There is a slight stain on the collar of the short-sleeved undershirt, but it's not very noticeable. Thank you for your understanding! #MIKIHOUSE #MikiHouse #BabyUndershirts #ShortSleevedUndershirt #CombinationUndershirt #FrontOpening
